I was visiting DC and had a lovely, first time, session with a young K-girl. I use a trimix injection and my general routine when mongering is to either inject in a bathroom in the hotel before I go up to the room, or excuse myself after we meet and use their bathroom. I like the former more as I don’t feel rushed or pressured, and I suspect that some deviations in injection technique can affect the quality of erection.  On this occasion I excused myself to the bathroom and injected.  After that there was a prolonged—but very nice —shower/prep routine before the actual festivities began. I found by that time my erection had diminished somewhat. Sex was still very enjoyable, and I actually lasted quite a while, but I like to put to good use that first rush of extremely hard erection. I guess in the future I will excuse myself after the shower to do the injection, but it does seem awkward, plus there was a language barrier (similar to many of the Hispanic lady’s I’ve seen before) so it’s hard to explain what I’m doing. I wonder if anyone else deals with this in a more creative or smoother way? Thanks!
